Fiber optic splicer closure is the equipment used to offer room for fusion splicer optical fibers. It also provides protection for fused fiber joint point and fiber cables. There are mainly two types of closures: vertical type and horizontal type. A large variety of fiber splice closures are designed for different applications, such as aerial, duct fiber cables and direct burial. Generally speaking, they are usually used in outdoor environment, even underwater.

Fiber Optic Splice Closure Types

For outside plant splice closure, there are two major types: horizontal type and vertical type.

Horizontal type splice closures look like flat or cylindrical case. They provide space and protection for Fiber optic splicer and joint. They can be mounted aerial, buried, or for underground applications. Horizontal types are used more often than vertical type (dome type) closures.

Most horizontal fiber closure can accommodate hundreds of fiber connections. They are designed to be waterproof and dust proof. They can be used in temperature ranging from -40°C to 85°C and can accommodate up to 106 kpa pressure. The cases are usually made of high tensile construction plastic.
